Effects of a Nutraceutical Multicompound, with Probiotics, Hericium, PEA, and Undaria in Patients with Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a functional gastrointestinal condition. Probiotics and other nutraceutical compounds can have specific indications in the context of IBS. A retrospective analysis was conducted on 123 IBS patients in order to evaluate the effects of an oral probiotic-based dietary supplement (Colicron, one cps/day for 4 wk) on stool consistency and pain intensity. Different time points were defined as follows: baseline (T0), 2 wk of treatment (T2), and 4 wk of treatment (T4). Stool consistency was assessed by using the Bristol Stool Scale. Pain intensity was evaluated by the Visual Analogue Scale (VAS). Patients who were initially categorized as normal retained regular bowel movements throughout the study. Both patients with constipation and diarrhea showed an improvement in the Bristol Stool Scale. The score increased from 1.5 ± 0.5 to 3.3 ± 0.7 (p < 0.001) and decreased from 6.5 ± 0.7 to 4.3 ± 0.9 (p < 0.001) at T4, respectively, compared to T0. The VAS score for pain in the pooled IBS patients improved from 6.7 ± 2.2 to 2.8 ± 1.9 at T0 vs T4 (p < 0.001), with a similar trend also observed when patients were categorized based on stool consistency: normal (from 5.2 ± 1.9 to 2.9 ± 1.7), constipation (from 7.5 ± 1.3 to 3.2 ± 2.2), and diarrhea (6.7 ± 2.3 to 2.5 ± 1.9) (p < 0.001).Colicron could be useful in symptom relief, reducing abdominal pain and improving stool consistency of IBS patients. However, further controlled clinical trials are needed to confirm these preliminary findings.

Effects of 24/7 palliative care consultation availability on the use of emergency department and emergency medical services resources from non-oncological patients: a before-and-after observational cohort study.

OBJECTIVES: The non-oncological population is relatively under-represented among end-of-life (EOL) patients managed by palliative care (PC) services, and the effects of different PC delivery models are understudied in this population.This retrospective observational study on routinely collected data aimed at evaluating the effects of the extension from workday-only to 24/7 mixed hands-on and advisory home PC service on emergency department (ED) access and emergency medical services (EMS) interventions needed by non-oncological patients during their last 90 days of life, and their probability to die in hospital. METHODS: A before-and-after design was adopted comparing preimplementation and postimplementation periods (2018-2019 and 2021-22).We used a difference-in-differences approach to estimate changes in ED access and EMS intervention rates in the postintervention period through binomial negative regression. The oncological population, always exposed to 24/7 PC, was used as a control. A robust Poisson regression model was adopted to investigate the differences regarding hospital mortality. The analyses were adjusted for age, sex and disease grouping by the system involved. Results were reported as incidence rate ratios (IRRs) and ORs. RESULTS: A total of 2831 patients were enrolled in the final analysis.After the implementation of 24/7 home PC, both ED admissions (IRR=0.390, p<0.001) and EMS interventions (IRR=0.413, p<0.001) dropped, as well as the probability to die in hospital (OR=0.321, p<0.001). CONCLUSIONS: The adoption of a 24/7 mixed hands-on and advisory model of home PC could have relevant effects in terms of ED access and EMS use by non-oncological EOL patients under PC. TRIAL REGISRATION NUMBER: NCT05640076.

Recognition in Emergency Department of Septic Patients at Higher Risk of Death: Beware of Patients without Fever.

Background and Objectives: Chances of surviving sepsis increase markedly upon prompt diagnosis and treatment. As most sepsis cases initially show-up in the Emergency Department (ED), early recognition of a septic patient has a pivotal role in sepsis management, despite the lack of precise guidelines. The aim of this study was to identify the most accurate predictors of in-hospital mortality outcome in septic patients admitted to the ED. Materials and Methods: We compared 651 patients admitted to ED for sepsis (cases) with 363 controls (non-septic patients). A Bayesian mean multivariate logistic regression model was performed in order to identify the most accurate predictors of in-hospital mortality outcomes in septic patients. Results: Septic shock and positive qSOFA were identified as risk factors for in-hospital mortality among septic patients admitted to the ED. Hyperthermia was a protective factor for in-hospital mortality. Conclusions: Physicians should bear in mind that fever is not a criterium for defining sepsis; according to our results, absence of fever upon presentation might be indicative of greater severity and diagnosis of sepsis should not be delayed.

An Italian registry of chest pain patients in the emergency department: clinical predictors of acute coronary syndrome.

BACKGROUND: The aim of this study was to describe the population of patients arriving in several Italian Emergency Departments (EDs) complaining of chest pain suggestive of acute coronary syndrome (ACS) in order to evaluate the incidence of ACS in this cohort and the association between ACS and different clinical parameters and risk factors. METHODS: This is an observational prospective study, conducted from the 1st January to the 31st December 2014 in 11 EDs in Italy. Patients presenting to ED with chest pain, suggestive of ACS, were consecutively enrolled. RESULTS: Patients with a diagnosis of ACS (N.=1800) resulted to be statistically significant older than those without ACS (NO ACS; N.=4630) (median age: 70 vs. 59, P<0.001), and with a higher prevalence of males (66.1% in ACS vs. 57.5% in NO ACS, P<0.001). ECG evaluation, obtained at ED admission, showed new onset alterations in 6.2% of NO ACS and 67.4% of ACS patients. Multiple logistic regression analysis showed that the following parameters were predictive for ACS: age, gender, to be on therapy for cardio-vascular disease (CVD), current smoke, hypertension, hypercholesterolemia, heart rate, ECG alterations, increased BMI, reduced SaO2. CONCLUSIONS: Results from this observational study strengthen the importance of the role of the EDs in ruling in and out chest pain patients for the diagnosis of ACS. The analysis put in light important clinical and risk factors that, if promptly recognized, can help Emergency Physicians to identify patients who are more likely to be suffering from ACS.

Short and long-term mortality of patients presenting with bleeding events to the Emergency Department.

BACKGROUND: Death of patients presenting with bleeding events to the Emergency Department still represent a major problem. We sought to analyze clinical characteristics associated with worse outcomes including short- and long-term death, beyond antithombotic treatment strategy. METHODS: Patients presenting with any bleeding events during 2016-2017years were enrolled. Clinical parameters, site of bleeding, major bleeding, ongoing anti-thrombotic treatment strategy and death were collected. Hard 5:1 propensity score matching was performed to adjust dead patients in baseline characteristics. Endpoints were one-month and one-year death. RESULTS: Out of 166,000 visits to the Emergency Department, 3.050 patients (1.8%) were enrolled and eventually 429 were analyzed after propensity. Overall, anticoagulants or antiplatelets were given to 234(54%). Major bleeding account for 111(26%) patients, without differences between those taking anticoagulants or antiplatelets versus others. Death at one-month and one-year was 26(6%) and 72(17%), respectively. Independent predictors of one-month death were major bleeding (Odds Ratio, OR 26, p<0.001), female gender (OR 7, p<0.001) and white blood cells (OR 1.2, p=0.01); of one-year were major bleeding (OR 7, p<0.001), age (OR 1.1, p<0.001) and female gender (OR 2.3, p=0.043). Of note, death rate of gastrointestinal and intracranial bleeding where higher than others (p<0.001). Overall mortality was approximately 40% on one-month; 60% in older patients and 80% in female gender with CHA2D2VASC-score≥2. Receiver operator characteristics analysis showed larger areas for major bleeding and age (0.75 and 0.72, respectively) over others; p<0.05 on C-statistic. CONCLUSIONS: In patients with bleeding events, death rate was driven by major bleeding on short-term and older age on long-term. Among dead patients mortality was approximately 40% on one-month; 60% in older patients, and 80% in female gender.

Acute Heart Failure in the Emergency Department: the SAFE-SIMEU Epidemiological Study.

BACKGROUND: Patients with acute heart failure (AHF) have high rates of attendance to emergency departments (EDs), with significant health care costs. OBJECTIVES: We aimed to describe the clinical characteristics of patients attending Italian EDs for AHF and their diagnostic and therapeutic work-up. METHODS: We carried out a retrospective analysis on 2683 cases observed in six Italian EDs for AHF (January 2011 to June 2012). RESULTS: The median age of patients was 84 years (interquartile range 12), with females accounting for 55.8% of cases (95% confidence interval [CI] 53.5-57.6%). A first episode of AHF was recorded in 55.3% (95% CI 55.4-57.2%). Respiratory disease was the main precipitating factor (approximately 30% of cases), and multiple comorbidities were recorded in > 50% of cases (history of acute coronary syndrome, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, valvular heart disease). The treatment was based on oxygen (69.7%; 67.9-71.5%), diuretics (69.2%; 67.9-71.5%), nitroglycerin (19.7%; 18.3-21.4%), and noninvasive ventilation (15.2%; 13.8-16.6%). Death occurred within 6 h in 2.5% of cases (2.0-3.1%), 6.4% (5.5-7.3%) were referred to the care of their general practitioners within a few hours from ED attendance or after short-term (< 24 h) observation 13.9% (12.6-15.2%); 60.4% (58.5-62.2%) were admitted to the hospital, and 16.8% (15.4-18.3%) were cared for in intensive care units according to disease severity. CONCLUSIONS: Our study reporting the "real-world" clinical activity indicates that subjects attending the Italian EDs for AHF are rather different from those reported in international registries. Subjects are older, with a higher proportion of females, and high prevalence of cardiac and noncardiac comorbidities.

Acute heart failure in the emergency department: a follow-up study.

Acute heart failure (AHF) is a major public health issue due to high incidence and poor prognosis. Only a few studies are available on the long-term prognosis and on outcome predictors in the unselected population attending the emergency department (ED) for AHF. We carried out a 1-year follow-up analysis of 1234 consecutive patients from selected Italian EDs from January 2011 to June 2012 for an episode of AHF. Their prognosis and outcome-associated factors were tested by Cox proportional hazard model. Patients' mean age was 84, with 66.0% over 80 years and 56.2% females. Comorbidities were present in over 50% of cases, principally a history of acute coronary syndrome, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, valvular heart disease. Death occurred within 6 h in 24 cases (1.9%). At 30-day follow-up, death was registered in 123 cases (10.0%): 110 cases (89.4%) died of cardiovascular events and 13 (10.6%) of non-cardiovascular causes (cancer, gastrointestinal hemorrhages, sepsis, trauma). At 1-year follow-up, all-cause death was recorded in 50.1% (over 3 out of 4 cases for cardiovascular origin). Six variables (older age, diabetes, systolic arterial pressure <110 mm/Hg, high NT pro-BNP, high troponin levels and impaired cognitive status) were selected as outcome predictors, but with limited discriminant capacity (AUC = 0.649; SE 0.015). Recurrence of AHF was registered in 31.0%. The study identifies a cluster of variables associated with 1-year mortality in AHF, but their predictive capacity is low. Old age and the presence of comorbidities, in particular diabetes are likely to play a major role in dictating the prognosis.

International perspectives on emergency department crowding.

The maturation of emergency medicine (EM) as a specialty has coincided with dramatic increases in emergency department (ED) visit rates, both in the United States and around the world. ED crowding has become a public health problem where periodic supply and demand mismatches in ED and hospital resources cause long waiting times and delays in critical treatments. ED crowding has been associated with several negative clinical outcomes, including higher complication rates and mortality. This article describes emergency care systems and the extent of crowding across 15 countries outside of the United States: Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Iran, Italy, The Netherlands, Saudi Arabia, Catalonia (Spain), Sweden, and the United Kingdom. The authors are local emergency care leaders with knowledge of emergency care in their particular countries. Where available, data are provided about visit patterns in each country; however, for many of these countries, no national data are available on ED visits rates or crowding. For most of the countries included, there is both objective evidence of increases in ED visit rates and ED crowding and also subjective assessments of trends toward higher crowding in the ED. ED crowding appears to be worsening in many countries despite the presence of universal health coverage. Scandinavian countries with robust systems to manage acute care outside the ED do not report crowding is a major problem. The main cause for crowding identified by many authors is the boarding of admitted patients, similar to the United States. Many hospitals in these countries have implemented operational interventions to mitigate crowding in the ED, and some countries have imposed strict limits on ED length of stay (LOS), while others have no clear plan to mitigate crowding. An understanding of the causes and potential solutions implemented in these countries can provide a lens into how to mitigate ED crowding in the United States through health policy interventions and hospital operational changes.

Interleukin-6 is a stronger predictor of total and cardiovascular mortality than C-reactive protein in haemodialysis patients.

BACKGROUND: Despite the well known association between interleukin-6 (IL-6) and cardiovascular mortality, no study has so far verified whether IL-6 adds prognostic information to that provided by C-reactive protein (CRP). METHODS: A cohort of 218 haemodialysis patients from four different dialytic centres was followed-up retrospectively. Plasma IL-6 and CRP concentrations were determined. Full information on co-morbidities was available in 162 patients. RESULTS: With respect to the lowest quartile (< 3.6 pg/ml for IL-6, and < 2.2 mg/l for CRP), the crude relative risk (RR) of death from all causes of the upper quartile (> 13.9 pg/ml for IL-6, and > 12.8 mg/l for CRP) was 5.20 (95% confidence interval 2.06-13.011) for IL-6 and 3.16 (1.41-7.12) for CRP. When both variables were included, the estimates were 4.10 (1.30-12.96) for IL-6 and 1.29 (0.47-3.57) for CRP. As to continuous variables, the relationship between both variables and mortality tended to level off for the highest values, but became fairly linear after log transformation of the variables. For one unit SD of the log (variable), the RR was 2.09 (1.52-2.88) for IL-6 and 1.66 (1.23-2.24) for CRP. When they were included in the same model, the estimates were 1.90 (1.18-2.82) for IL-6 and 1.16 (0.81-1.66) for CRP. CONCLUSIONS: IL-6 has a stronger predictive value than CRP for cardiovascular mortality and provides independent prognostic information, while conveying most of that provided by CRP.

The role of quantitative myocardial contrast echocardiography in the study of coronary microcirculation in athlete's heart.

Quantitative myocardial contrast echocardiography was performed with harmonic power Doppler analysis using the background subtraction and Levovist (Schering AG, Berlin, Germany) as contrast agent in a triggered modality. Quantitative analysis of echocontrast was performed offline with PC software, obtaining the transit curves of microbubbles through the coronary capillary system. Coronary microcirculation in athletes showed a behavior substantially comparable with control participants, although at a higher level. Training determines a physiologic left ventricular hypertrophy that counterbalances the dilatation in the left ventricular chambers because of the higher blood volume in athletes compared with control participants. Angiogenesis and several functional adaptations (relaxation of small coronary arteries, increased production of nitric oxide by the coronary endothelium, or both), represent the potential mechanisms that allow an optimal distribution of oxygen and of substrates to the hypertrophied myocardium of the athletes.

Excess aldosterone is associated with alterations of myocardial texture in primary aldosteronism.

Hyperaldosteronism has been causally linked to myocardial interstitial fibrosis experimentally, but it remains unclear if this link also applies to humans. Thus, we investigated the effects of excess aldosterone due to primary aldosteronism (PA) on collagen deposition in the heart. We used echocardiography to estimate left ventricular (LV) wall thickness and dimensions and for videodensitometric analysis of myocardial texture in 17 consecutive patients with PA and 10 patients with primary (essential) hypertension who were matched for demographics, casual blood pressure, and known duration of hypertension. The groups differed in serum K+, ECG PQ interval duration, plasma renin activity, and aldosterone levels (all P< or =0.002) but not for casual blood pressure values, demographics, and duration of hypertension. Compared with hypertensive patients, PA patients showed a higher LV mass index (53.7+/-1.8 versus 45.5+/-2.0 g/m(2.7); P=0.008) and lower values of the cyclic variation index of the myocardial mean gray level of septum (CVI(s); -12.02+/-5.84% versus 6.06+/-3.08%; P=0.012) and posterior wall (-11.13+/-6.42% versus 8.63+/-9.62%; P=0.012). A regression analysis showed that CVI(s) was predicted by the PQ duration, supine plasma renin activity, plasma aldosterone, and age, which collectively accounted for approximately 36% of CVI(s) variance. PA is associated with alterations of myocardial textures that suggest increased collagen deposition and that can explain both the dependence of LV diastolic filling from presystole and the prolongation of the PQ interval.

Ultrasonic tissue characterization and Doppler tissue imaging in the analysis of left ventricular function in essential arterial hypertension: a preliminary study.

It is not known if diastolic abnormalities are independent of systolic dysfunction in arterial hypertension. We studied three groups of 10 male subjects of comparable mean age (31.6 +/- 3.5 years), weight, and height: Athletes (A) (cyclists), essential hypertensive patients (H), and controls (C). Ultrasonic myocardial integrated backscatter signals (IBS) of the septum and the posterior wall were analyzed, while the systo-diastolic variation of the backscatter was considered as a cyclic variation index (CVI(ibs)). Myocardial velocities across the left ventricular major axis were sampled at septum and lateral wall levels by pulsed-wave Doppler tissue imaging (DTI). CVI(ibs) at the septum and the posterior wall were significantly lower in the hypertensive group in comparison with athletes and controls, who were comparable. Early diastolic myocardial velocity (E(m)) of the lateral wall and of the septum were significantly lower in hypertensives, while the late diastolic myocardial velocity (A(m)) was significantly higher in hypertensives in comparison with athletes. The E(m)/A(m) at the septum level was significantly lower in hypertensives in comparison with athletes and controls. Significant correlations were found between CVI and DTI parameters: CVI(ibs) and E(m)/A(m) septum (r = 0.50, P < 0.002). Furthermore, significant correlations were found between mean arterial pressure (MAP) and E(m)/A(m) septum (r = - 0.65, P < 0.001). Ultrasonic tissue characterization with the intrinsic contractility study and the evaluation of the regional diastolic function should, therefore, represent a new integrated diagnostic modality for the evaluation of left ventricular hypertrophied intramyocardial function. This study demonstrated that diastolic abnormalities of left ventricular function, in arterial hypertension, are related and progress with systolic intrinsic dysfunction.
